Abstract

The invention discloses a manufacturing process of a touch film. The touch film comprises a transparent base material, a sensing layer and a writing layer; a UV printing layer is obtained by UV printing material under ultraviolet irradiation, and the UV printing material is obtained by the following steps: mixing aliphatic polyurethane triacrylate, 1, 6-hexanediol diacrylate, ethylene glycol diglycidyl ether, castor oil polyglycidyl ether and alkyl modified organosiloxane into a stirring dispersion machine, and mixing at a stirring speed of 400-600r / min for 10-15min to obtain a material; and feeding the obtained material 2 into the bead mill, and grinding until the particle size is 300-400nm to obtain the UV printing material. According to the manufacturing process of the touch film, the crosslinking rate of all components in the UV printing material is improved, so that the UV printing material can be cured without too much heat energy, and the oxygen inhibition phenomenon of the UV printing material is effectively avoided.

Description

technical field [0001] The invention relates to a touch film, in particular to a manufacturing process of the touch film. Background technique [0002] UV light curing technology has the advantages of fast curing speed, high production efficiency, good mechanical and physical properties, less pollution, energy saving, etc., and is known as a green technology. With the increasing emphasis on environmental protection and the development of science and technology, the UV curing market is developing rapidly and is widely used in coatings, adhesives, inks, electronic packaging, glass, dental restoration, photolithographic imaging, and biomedicine. Although UV curing technology has made a lot of progress, there are still some problems in application, such as serious oxygen inhibition phenomenon in the existing UV curing system, low curing hardness, high viscosity and poor stability. [0003] Oxygen inhibition refers to the phenomenon that in the free radical photopolymerization s...
